Moreover, the pointing apparatus 200 and the user terminal 300 may beconnected by one of the various wireless communication schemes, and maymutually transmit and receive data.

Data, which is shared by the display apparatus 100, the pointingapparatus 200, and the user terminal 300, may be various kinds of datasuch as a real-time broadcast, a movie, a music, a photograph, adocument file, contents on demand (COD), a game, a news, a video call,an application, etc.

According to an embodiment of the present invention, the pointingapparatus 200 including a data transmission means and a memory is usedas a medium for data exchange between the display apparatus 100 and theuser terminal 300. An information transfer scenario using the pointingapparatus 200 is as follows.

For example, when the pointing apparatus 200 is powered on, the pointingapparatus 200 searches the display apparatus 100 to perform a paringoperation, and is connected to the network.

The display apparatus 100 displays transfer-desired information on ascreen. In this state, when the pointing apparatus 200 is brought intocontact with a partial region of the screen, the display apparatus 100recognizes a position pointed by the pointing apparatus 200 to identifythe information displayed at the recognized position.

When a user pushes a copy button of the pointing apparatus 200, thedisplay apparatus 100 transmits the identified information to thepointing apparatus 200, and the transmitted information is stored in amemory included in the pointing apparatus 200 (in a case where aplurality of pieces of information are displayed on a screen, when acopy operation is sequentially performed for the plurality of pieces ofinformation, the pieces of information are sequentially stored within acapacity of the memory included in the pointing apparatus 200).

Subsequently, the user executes an application which is to be processedby its own user terminal 300, and then, when the user pushes a pastebutton of the pointing apparatus 200, information stored in the memoryof the pointing apparatus 200 is transmitted to the user terminal 300(when a plurality of pieces of information are stored in the memory ofthe pointing apparatus 200, all the pieces of information may betransmitted to the user terminal 300 by repeatedly performing a pasteoperation).

According to the above-described embodiment, information of a digitalsignage or a public display apparatus 100 may be collected by a mediumwhich is the pointing apparatus 200 such as a smart pen, and thecollected information (data) may be simply transmitted to a plurality ofuser terminals 300 respectively possessed by individuals.

According to the embodiment of the present invention, apparatuses mayexchange information through only the copy operation and the pasteoperation without using an inconvenient means unlike an email, and mayimmediately use the information. Also, a plurality of pieces ofinformation are quickly collected by using an informationcollection/storage apparatus (which is a smart pen) without needing toalways carry a portable device, and later, the collected information maybe used when necessary.

In another embodiment, without using a method in which informationtransmitted from the display apparatus 100 is stored in the memory ofthe pointing apparatus 200, the information may be stored in a storagespace of an external cloud server apparatus network-connected to thedisplay apparatus 100.

In such a method, when the user pushes the copy button of the pointingapparatus 200, information of the display apparatus 100 is nottransmitted to the pointing apparatus 200 but is transmitted to astorage space of a network designated by the pointing apparatus 200.
